SAFETY-GUARD ATTACHMENT FOR RAZOR-BLADES.

SPECIFICATION formingpart of I Letters Patent N 0. 649,126, dated May 8,.1900. Application filed November 23, 1899. Serial No. 737,995- (NOmodel- T0 aZZ whom it may concern:

Be it known that I, LEON FLINKER; a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented a certain new and useful Improvement in Safety-GuardAttachments for Razor-Blades, of which the following is a specification.

My invention relates to the improvement of safety attachments forrazor-blades; and the objects of my invention are to provide a simple,reliable, and inexpensive attachment of this class which may be readilyattached to or removed from an ordinary razor-blade and which willoperate as a guard or shield against cutting of the skin, to provideimproved means of adjustably supporting the guard and retaining the sameat a desirable distance from the side of the blade, and to produce otherimprovements, the details of construction of which will be more fullypointed out hereinafter. These objects I accomplish in themannerillustrated in the accompanying drawings, in which Figure 1 is aview in perspective of a razor the blade of which is provided with myim- Fig. 2 is a side elevation of the blade having the guard thereon.Fig. 3 is a sectional view on line 00 0c of Fig. 2; and Fig. at is anenlarged transverse section of the guard or yoke-bar, illustrating amodified construction to be hereinafter explained.

Similar numerals refer to similar parts throughout the several Views.

In carrying out my invention I employ a substantially yoke-shaped guard,of metal or other suitable material, of which 1 is the horizontal bar,and 2 the parallel arms, which project, respectively, from points nearthe ends of said bar. In constructing the bar 1 I preferably form theinner face thereof and upper side with inwardly-projecting lugs 3,- thelatter being arranged at suitable intervals. 5 represents tworazor-blade-clamping bodies, one of which is adjustably connected witheach of the arms 2 in the manner hereinafter described. As indicated inthe drawings, each of the clamps 5 is in the nature of a metallicstrip,which is formed with a double bend, producing a downturned loopportion 6 and an upturned loop portion 7, the former being in the natureof a rounded loop, while the latter is bent inward to a partialflattened form. As indicated MS, I form in the lower side and partiallyin the outer face of the loop portion 7 a slotted opening, and, asindicated at 9,'I form in the upper edge portion of the outturned member7, in alinement with said opening 8, a recess or notch. In the lower endor termination of the loop portion 6 I form an upturned hinge-roll 10,which is divided by a slotted opening or central recess formed partiallyin said roll and partially in the adjoining end portion of the loopportion 6. Bearing in each pair of these hinge-rolls are the endportions of a transverse hinge-pin 11, on which is mounted centrally thehead portion of a curved cam-lever 12, the head of the latter beyond itspivot or hinge point being adapted to project within the loop 6 whensaid lever is thrown upward to the position indicated in the drawings.

On the inner face of the yoke-bar 1 I preferably form transversecorrugations 13, and on this corrugated face, at equidistant points fromthe outer edge of the bar 1, I form two or more small indentations 14.

The manner of connecting the yoke with the blade-clamps consists ininserting the yoke-arms 2 through the slotted openings 8 of said clampsand thence upward between the inner and outer portions of the loop 7,these loops being sufficiently flattened and having sufficientresiliency to form friction-clamps for said yoke-arms, retaining thelatter in the positions to which they are forced.

In order to illustrate the use of my device, I have shown the same inposition for use on a razor-blade, which is indicated at 15. It will beseen from this illustration that the back of the blade is adapted to beinserted within the loop portions 6 of the clamps 5, said blade beingadapted to be temporarily locked in this position by pressing upward thecam-lever arms 12 until the heads thereof contact with the outer side ofthe blade with sufficient firmness to bind the latter Within said loops.

In order to get a proper adjustment of the guard with relation to thecutting edge of the razor-blade, I have provided the guide-indentations14:, which indicate the line to which said blade edge should extend.

It will be observed that the inwardly-prol bar 1 and arms 2, ofclamping-bodies 5 each jecting lugs 3, which I form with the bar 1,will, by contact with the side of the razorblade, serve to hold the bar1 in desirable parallel alinement with said blade and away from thelatter. In Fig. 4 of the drawings I have shown as a substitute for eachof the fixed lugs 3 a set-screw 16, the latter having threadedengagements with screw-holes formed in said bar 1 and the ends of thescrews being adapted to abut against the razor-blade. In this manner thedistancebetween the yoke-bar and razor-blade may be regulated at will. I

In utilizing a razor having my improved guard thereon it will beobserved that the corrugations 13, which I preferably form in the faceof the bar 1, will facilitate the passage of the lather between theguard and blade.

From the construction above described it.

will be seen that by forcing inward or outward the arms 2 of the yokethe position of the bar 1 may be regulated for use on razors havingblades of various sizes and that the means of attaining this regulationor adj nstment are exceedingly simple and positive.

Having now fully described my-inveution, what I claim, and desire tosecure by Letters Patent, is-

1. In a safety-guard for razors, the combination with the yoke-bodyconsisting of the comprising upwardly and downwardly bent loop portions,the loop 7 having an opening through its inner end adapted to engagearms 2, and a cam-lever fulcrumed in the outer portion of the loop 6,substantially as specified.

2; In a safety-guard attachment for razorblades, the combination with ayoke-body consisting of a bar 1 having projections on its inner facearranged at intervals and arms 2,

of clamping-bodies 5 each consisting of an upwardly and downwardly bentloop portion, said upwardly-bent loop being provided with an opening andadapted to receive and clamp the arms of said yoke and a cam-leverfulcrum ed in the downwardly-bentloop portion, substantially asspecified.

3. In a safety-guard attachment for razorblades, the combination with ayokebody consisting of the bar 1 and arms 2, said bar having separatedindentations orguide-marks 14 on its inner face, of clamping-bodies 5having oppositely-bent loop portions adapted to respectively embrace theback of a razorblade and the arms of said yoke-body, substantially asspecified.
